• What is the cause and solution for SAP error message LIS_SRV024 - Connections were generated with the 'Trusted System' attribute ?

  The SAP error message LIS_SRV024 indicates that connections were generated with the 'Trusted System' attribute. This typically occurs in the context of SAP Landscape Management or when dealing with system connections that are configured to trust each other for various operations, such as data transfer or remote function calls.
  Cause:
  
  Trusted System Configuration: The error usually arises when a system is trying to establish a connection to another SAP system that is configured as a trusted system. This can happen if the connection settings are not properly configured or if there are issues with the trust relationship between the systems.
  Missing or Incorrect Configuration: The trust relationship may not be correctly set up in the SAP system landscape, leading to the error when attempting to use the connection.
  Authorization Issues: The user or service account attempting to establish the connection may not have the necessary authorizations to use the trusted connection.
  
  Solution:
  
  
  Check Trusted System Configuration:
  
  Go to transaction SM59 (RFC Destinations) and check the configuration of the RFC destination that is causing the error.
  Ensure that the "Trusted System" attribute is correctly set up for the intended systems.

  Authorization Check:
  
  Verify that the user or service account has the necessary authorizations to establish a trusted connection. This may involve checking roles and profiles assigned to the user.
  
  
  
  System Logs:
  
  Check the system logs (transaction SM21) for any additional error messages or warnings that may provide more context about the issue.
  
  
  
  Network Configuration:
